Implant

Abstract

The present invention relates to an implant for determining a pressure difference inside a bodily lumen, comprising: an implantable body, the implantable body comprising a first conductive element and a second conductive element, the first and second conductive elements being electrically insulated relative to each other, first and second pressure sensors, the first and second pressure sensors being arranged for measuring a pressure occurring inside the body, the first and second pressure sensors being arranged at different locations, wherein the first pressure sensor is arranged for sending the pressure to a remote read-out device by means of being coupled to the first conductive element, with the first conductive element serving as an antenna, and wherein the second pressure sensor is arranged for sending the pressure to a remote read-out device by means of being coupled to the second conductive element, with the second conductive element serving as an antenna.

1 . An implant for determining a pressure difference inside a bodily lumen, comprising:
 an implantable body, the implantable body comprising a first conductive element and a second conductive element, the first and second conductive elements being electrically insulated relative to each other,   first and second pressure sensors, the first and second pressure sensors being arranged for measuring a pressure occurring inside the body, the first and second pressure sensors being arranged at different locations,   wherein the first pressure sensor is arranged for sending the pressure to a remote read-out device by means of being coupled to the first conductive element, with the first conductive element serving as an antenna, and wherein the second pressure sensor is arranged for sending the pressure to a remote read-out device by means of being coupled to the second conductive element, with the second conductive element serving as an antenna, wherein the implantable body comprises a stent, wherein the stent is a wire stent comprising a section made of a helically wound wire, wherein the first conductive element and/or the second conductive element are part of the helically wound wire, wherein the first conductive element and the second conductive element are connected to each other by means of an insulating connector sheath.   
     
     
         2 . The implant according to  claim 1 , wherein the first conductive element and/or the second conductive element are made of a single piece of wire. 
     
     
         3 . The implant according to  claim 1 , wherein the stent further comprises a section made of a woven wire. 
     
     
         4 . The implant according to  claim 1 , the stent being self-expanding. 
     
     
         5 . The implant according to  claim 1 , wherein the first and the second pressure sensors are arranged at opposite longitudinal ends of the stent. 
     
     
         6 . The implant according to  claim 1 , wherein the stent is at least partially covered with a covering material to form a stent graft. 
     
     
         7 . The implant according to  claim 6 , wherein the stent graft is a TIPS stent graft.
